Hi Antonio, I tried your suggestion, end changing the "name" with a "string" one, whit "column2" worked (I have problem uploading picture now but I'll try again later) and If I use the "get symbol from folder" node, even if set a column style, it does not work, (at least I was not able, may be I'm missing something).
My goal now is to be able to insert a "structural member" object, not the "column" object.
